Included with every book
The Blue Index
A private archive of your handwritten pages. It reads what you wrote and keeps it searchable, a week later, a year later, three books later.
Photograph a page and the original is kept exactly as it is. Most pages aren't worth keeping; it exists for the ones that are.
And it's yours to take anywhere
Ask your own AI about your own thinking.
Connect your Blue Index to the model you already use. Nothing is locked inside an app you have to keep paying for.

ChatGPT
Gemini
Whatever comes next
The Blue Index runs an MCP server. Any AI client that speaks it can read your archive, with your permission and only what you allow.
Free with the book. No subscription, and there never will be one.
Before you ask
Do I have to use the white pen?
Yes. Anything darker disappears into the page. That's the trade: a book that dictates its pen, in exchange for pages nothing else looks like. It ships with the book, and refills are always in stock.
How does the AI connection work?
The Blue Index runs an MCP server, the open standard for giving an AI client access to your own data. Connect it once in Claude, ChatGPT, Gemini or anything else that supports MCP, and you can ask about your own pages in the tool you already use. You choose what it can see, and you can disconnect it at any time.
Is there a subscription?
No. The Blue Index is free with the book, permanently, and you can connect it to your own AI rather than ours. We sell objects, not access.
Where do you ship, and can I return it?
Worldwide, from Stockholm. Duties and taxes are shown at checkout. You have fourteen days to change your mind, unused, for any reason.
When does it ship?
1 September 2026. This is a pre-order for a numbered edition. If that date slips, you'll hear it from us before you have to ask.
